I borrowed this from another LT1 related forum and thought I would post it up. Any positive criticism is welcome. Maybe we can add some pics to this. Proceed at your own risk. BE SAFE!

Flush and Refill Power Steering System

Flush procedure: Raise vehicle so that front wheels are off the ground and free to turn. Remove steering gear outlet hose (should be the hose that goes from the rack to the reservoir #33) at fluid reservoir and plug the reservoir port . You may want to unmount the reservoir to make it easier to get to the hoses. Position the steering gear outlet hose (the one you just took off) toward a container to catch draining fluid. While an assistant is filling fluid reservoir, start and run engine at idle. Turn steering from lock to lock but do NOT hold it against the stops. Continue draining until all old fluid is cleared from system. About a quart of fluid is needed to flush the system. Unplug the port on the reservoir and reconnect reservoir hose. Turn engine off and fill reservoir to the "C" mark on the level indicator. Complete by following with bleeding procedure.

Bleed procedure: Ignition off Raise front wheels off the ground Turn wheel full left Fill reservoir to full cold and leave cap off With assistant checking fluid level, turn wheel lock to lock at least 20 times. Engine remains off. Check fluid while turning for signs of bubbles. If bubbles are seen check for any loose connections. Start engine. With engine idling, maintain fluid level. Reinstall cap. Return wheels to center and lower wheels to ground. Keep engine running for 2 minutes Turn wheels in both directions and verify that it is smooth, quiet, fluid at proper level, no leaks or bubbles.

And you did this WHY?

That hose always seems to be the nastiest one in the engine compartment.Only reason I'D touch that is when it gives up due to rust (just happened on the RMW)
